RIP anybody in a NYC or Tokyo high rise with a few thousand neighbors in wifi range.

I am pretty sure my Debian box that runs Kodi has fewer trackers than my TV.

Yes.

There is a lower volume of extraneous calls to advertising networks from an appletv box than from a Samsung or lg tv. Users see a lower volume of what they recognize as targeted ads (you gotta think about the confirmation bias here). The devices themselves can decode more complex stream types because they are spending less processing power taking screenshots and running image recognition models on them. A tv from a major manufacturer tends to cost more if it’s the “dumb” or digital signage variant, whereas a streaming box (that’s not like roku or whatever the bottom of the barrel option is) costs $100+.
